I built a bass trap for about $NZ80 from plans in Alton Everest's book on acoustics. Then I stuck it under the bed--there is a bed in my "studio". That fixed the bass because it resonates at 100 Hz. Everest also gives lots of tables for materials and sizes. You can build BBC mid-range panels too, just as simply. Using Audacity's tone generator I "squeaked" the room, but there was a nasty dip caused by the speaker's interaction with the wall. So I resorted to a good healthy handclap, which on Audacity let me see the shape of the decay and its causes. Better to fix the studio than tweak your equipment's frequency response.
